What are you looking for in order to determine if batter interference is called in this scenario.

R1 stealing
BR swings and his follow through brings him across the plate.
Catcher throws to 2nd.

Let's assume there is no contact between the batter and the catcher.

Are you looking to see if the catcher has to hesitate?
If he has to move around the batter?
Does it matter if has to throw around the batter?

Is the rule the same between FED and OBR?

Thanks
